Description.
Male (Figs 1 View Figure 1 - 4 View Figure 4 ). Head, pronotum, mesoscutum, metapectal-propodeal complex, petiole, antenna, and metasoma dark castaneous to black; wings hyaline. Head as long as wide and subquadrate, not globoid in lateral view. Clypeus with triangular median lobe, visible dorsally, lateral lobe reduced. Median clypeal carina delimited, lower than frons. Flagellomere longer than wide, with first flagellomeres larger than distal ones; flagellar pubescence erected; pedicel shorter than flagellomere I, apex dilated. Eye located touching mandibular base, glabrous, bulging. Frons weakly coriaceous, punctures large and sparse. Frontal line not visible. Ocellus large, salient. Frontal angle of ocellar triangle in obtuse angle. Anterior ocellus posterior to supra-ocular line. Occipital carina present. Dorsal pronotal area wider than long, weakly coriaceous, punctures small and sparse. Metafurcal pit oval. Posterior mesofurcal pit crown-shaped. Notaulus present, large, converging posteriorly, smooth. Parapsidal signum shorter than notauli. Forewing with three cells closed (C, R, 1Cu), distal flexion line visible, 2r-rs&Rs vein tubular, long, well pigmented, angled, not converging posteriorly to anterior margin, R1 vein tubular, long. Pterostigma enlarged, lanceolate. Mesoscutum-mesoscutellar sulcus present, posterior margin strongly incurved medially. Metanotum well-developed medially. Metapectal-propodeal disc not visible. Mesotibia without spines. Metasoma polished. Ninth abdominal segment with margin weakly incurved, undivided.
Female (Figs 1 View Figure 1 - 3 View Figure 3 , 5 View Figure 5 ). Head, pronotum, mesoscutum, metapectal-propodeal complex, petiole, antenna, and metasoma light to dark brown. Head longer than wide and rectangular, not globoid in lateral view. Clypeus with median lobe trapezoidal, visible dorsally, lateral lobe reduced. Median clypeal carina not visible. Flagellomere as long as wide, with first flagellomeres wider than distal ones; flagellar pubescence appressed; pedicel barrel shaped, as long as flagellomere I. Eye located almost touching mandibular base, glabrous, reduced, flat. Frons weakly coriaceous, punctures small and sparse. Frontal line not visible. Ocelli absent. Dorsal pronotal area smooth, longer than mesoscutellum medially. Metafurcal pit oval. Posterior mesofurcal pit oval. Anteromesoscutum with anterior margin straight. Notaulus absent. Parapsidal signum absent. Mesoscutum-mesoscutellar sulcus absent. Mesopleuron visible dorsally, broad. Apterous. Mesotibia spinose. Metapectal-propodeal disc long, broadly in contact with anteromesoscutum, anterior margin wider than posterior one, lateral margin almost parallel in dorsal view, weak constriction at spiracles present. Second abdominal segment without flap expanded laterally.
